Credit cards, charge cards, and other transaction instruments are commonly accepted today as a form of payment under a variety of circumstances. A transaction instrument may be used to complete a purchase in-person (e.g., at a retail store, a restaurant, or a hotel) by physically presenting a merchant with the transaction instrument. A transaction instrument may also be used to complete a purchase, without physically presenting the transaction instrument, by relaying information associated with the transaction instrument (e.g., account number, account name, expiration date, and billing address) to a merchant, such as though a computer or point of sale (POS) device. Examples of merchants that accept transaction account information as payment, without physically receiving the transaction instrument include Internet, telephone and mail order merchants.
